[Bimbofication, Transformation]

Serving as part of the Navies that fought back against the terrors under the sea was a duty that many would consider themselves proud of. Especially if it involved blasting those darned Sirens back to where they came from, so that peace could fall upon these blessed waters.

But not everyone really cared about how it felt to blast away with one’s cannons during a high speed skirmish. Not everyone cared about sailing straight through enemy fire and capsizing them in one fell swoop. And certainly not everyone actually cared about protecting the carriers that could bring them towards victory…

And most importantly of all, not everyone actually cared about doing all of that dumb ship business, especially not Mutsu! The black-haired and young-bodied Battleship was far more concerned about the matter at hand. The matter concerning life and death, and the continuation of a bloodline yet to form!

That’s right. She was talking about the love that had bloomed in her heart for her Admiral. He wasn’t the brightest nor was he the most ambitious, but he cared enough for the girls under his command even if they didn’t listen to him often. Even she couldn’t call herself utterly obedient in his presence, but it was that very same lack of respect that made her adore him. There was just one teeny, tiny problem with the love blooming in her young heart.

“Why can’t there be less titty monsters around here!?” The black-haired girl cried out as she stomped her feet into the floor, droplets of sweat bouncing off her skin while she opened the doors to the shopping district at the base. Whenever she got this mad and frustrated, there was only one person she could turn to…

Akashi. The green-haired snake of a girl who kept gouging everyone for their money and then some. At the same time, she was the kind of girl that you could go to and she’d give her unbiased opinion, as long as you tipped her a few gems beforehand.

“Mutsu, back again?” Akashi purred as she dusted off a couple of equipment boxes, humming to herself as she swayed from left to right. She needed to make sure all of her wares looked as spiffy as possible, otherwise she couldn’t get the Admiral to buy anything. Or she could just milk the money out of him, like she had done before. She’d prefer the easier route though.

The black-haired Battleship-kitty nodded, still visibly moping as she stomped up to the counter. “It’s not fair! Why are there so many big tittied dummies on the base!?” She shouted as her ears and her tail stood at attention, her fists slamming into the wooden furniture. “What does Admiral see in them?! Doesn’t he like us, Akashi?!”

“He likes everyone, you know that.” The usually tired-looking green-haired merchant said as she pawed at the guest. She didn’t talk for cheap. After her guest dropped a couple of gems into her oversized pawpad, she pocketed them and rested her head on her own palms. “Have ya tried getting bigger?” She suggested, not even missing a beat…

Mutsu blinked a couple of times, as if she had just heard something completely inane. “...I can do that?” And yet despite how weird it sounded, to the naturally curious Battleship, this was exactly what she was looking for. “Tell me, Akashi! Tell me what you know about making my boobies super mega huge!”

“It’ll cost ex-” Akashi quickly replied, only to let out a feline shriek as she felt a heavy bag of gems fall straight onto her tail. As elegantly tossed by her guest, who didn’t even bother trying to be subtle… “Don’t hurt the seller or you won’t get anything!”

The black-haired girl giggled a little as she rubbed the back of her head, while the green-haired merchant just grumbled and huffed. Now it was her turn to be in a prissy mood. “Just help me out, okay, Akashi? I promise to make it up to you! Like, I’ll get you the biggest cake that the others can make… or I can, uh…” She paused, tapping her chin… “I can ask Nagato if you can be the flagship for a bit!”

“No thanks.” The green-haired kitten turned the offer down as she motioned for her guest to follow her, as a band aid had quickly been wrapped around her bruise. “I don’t need that kind of stuff, you know. I just need cash, so we can keep the base well-supplied. And so the lot of you can get cute costumes too.” She purred as they made their way into a room in the back, one with a very bright ‘DO NOT ENTER’ label on the front.

Mutsu wobbled back and forth without any sign of stopping as the two went inside, only for a soft hum to ring throughout her ears. “What’s that noise, Akashi? Is it the thing that’s supposed to make me have super big boobies?” She asked, as the green-haired girl was already on her way out. “Hey, wait!”

Thankfully, Akashi wasn’t about to just leave her without an explanation. “I’ll give you the details, and then I expect another payment.” The green-haired girl stated before clearing her throat and pulling out a piece of paper, showing a very crude diagram of a smaller girl turning into a bigger girl. Scribbled with crayon, at that. “This machine is based on the retrofitting technology that the other bases use. With it, you can assume a bigger and better shape than ever before. I didn’t get to test it, but considering what the Admiral said when I managed to dig him out of it a few weeks back… It should work.” She explained, holding out her paw once more as she motioned for payment.

It didn’t take a second before she got that payment, in the form of a very loaded looking wallet with a cutesy sticker on top, a sticker with the Admiral’s name on it. “...Why do you have the Admiral’s wallet, Mutsu?” The positions were reversed yet again, as the green-haired girl tried to ask a question…

Which was immediately shut off by the doors to the machine closing on her, prompting her to shrug her shoulders. She just took this as a sign to turn everything up to the max settings, to the point where she wouldn’t be recognizable. Maybe then the Admiral would look at her… And not remember that his wallet was now in the merchant’s hands instead of the girl who pined for him.

The dial for breasts went up, as well as the butt and thigh dial that were closely adjacent to them. So did the natural beauty, ensuring that the girl inside would have a powerful sheen to her courtesy of whatever beams she’d be showered in. But there was one dial that she probably shouldn’t touch, the intelligence dial. When she tried it on one of the destroyers, it made her even ditzier than normal…

So of course she turned the dial all the way down to 0, just so that the girl wouldn’t bother her any longer. And as payback for making that bag of gems land on her tail. Served her right.

Mutsu giggled a little more as she twirled around in the big room, jumping to try and make the machine turn on. “Why won’t it start? Do I have to sit still? But I wanna get big boobs now!” The easily excitable Battleship cried out as she eventually hit the center…

“SHIPGIRL DETECTED” The loud, digitized and female voice echoed around her, causing the girl to stop in her tracks from the sound reverberating through her body. “PROCESS INITIATED. ALL SETTINGS MAXED OUT.” It declared, a loud siren filling the room as it lit up with bright red lights…

Not just from above either. There were a ton of red lights. And they weren’t the type that were just for alarm either, they were really eye-catching. Like they were trying to sneak into the girl’s mind the more she looked at them. In fact, she could see the lights even if her eyes were closed, which made it even harder to look away. Even if she rubbed away at her eyes, she couldn’t see a thing…

What Mutsu wasn’t aware of was the effects of the lights baking their way into her. They were warm, dangerously so. That warmth let all of her defenses, physical, mental and spiritual, fall into a complete lull. Which meant that the lights, specially designed to reconstruct living matter, could do whatever they wanted with her.

The process of it all started with her body. It was far, far too short for the settings that were enabled. So the overheating lights made her body shoot up in height, from the size of a short girl that looked like she belonged in school rather than in the army to something much more impressive. It wasn’t enough that she grew a few feet either, she needed to stand tall and proud, just like a proper flagship. By the time that she had finished growing, she was about two times her original size, if not a little taller than that.

Next came her curvature. Despite the growth to the rest of her body, she was still pitifully, awfully flat! That had to change, and fast. It came to her tits first, both of her breasts powerfully bursting out of her shrine maiden uniform despite how tightly it had been bound. Even the sarashi she had tried to wear earlier in the day to make it look like she had bigger breasts than she really did burst off, shredding to pieces as the kitty-weared girl let out a moan and a half.

Her buttocks followed suit, filling out as her uniform’s skirt pushed further and further up. There was absolutely no way that a proverbial shelf like hers could be contained under such a meager uniform, and the panties with the paw pads that she wore were equally invalidated, shredding into pieces of useless cloth that slowly drooped towards the floor below. All while her exposed elements started to grow wet and ready for something to play around with them…

Mutsu could feel her thighs growing slick, her dainty hands reaching down to grind up against her slit. Her heart was pounding through her chest, and her eyes were quickly turning into hearts. Hearts that weren’t colored like her normal eyes either, but rather a gentle green that was quite unlike her…

There was another setting that Akashi had turned on, as part of turning everything to max. It would change her irrevocably into a different type of Mutsu unit, one that she had occasionally seen in the books that her Admiral read. A tall and strong one, that stood alongside an equally strong looking Nagato…

It was no wonder that her kitty ears sunk into her head after that, nor that her hair turned from black to a gentle brown, the strands reaching right below her chin as she started panting and moaning. It felt really good to play with herself, so much so that she ignored every other part of her transformation while her assets started bouncing from her rapid movements…

Her clothes had outgrown her, but the lights that cooked away at her and completely melted her former self away, would serve to make her look the part of this other Mutsu. Whether it was her strained top expanding outward into something more compact. A simple white top that had a bit of a sash near the bottom, to prevent underboob and keep it pinned to her chest. Yet at the same time, thanks to her oversized bosom, it wouldn’t hold for long should she keep growing.. .Which was exactly the kind of appeal that she was headed for, the kind of girl who outgrew everything and threatened to grow even bigger where it mattered most.

Her skirt actually grew shorter during this transition, as the parts of her uniform that covered up her belly were completely stripped away. Sweat ran down her tummy, giving it a nice glistening sheen as she continued to grow hot, while her shortened skirt did little to cover up her buttocks. In fact, the only thing that kept her from completely exposing herself was a razor thin piece of underwear that only just hid parts of both holes… All while rubbing into her, turning her on more and more.

Mutsu’s head was a jumbled mess of memories that had been completely melted out of her, in the form of a cozy pink liquid pouring out of her ears, as well as pure arousal. She was horny, and she was ready to show it off to anybody that would let her. Whether it was a friend or a foe, she wouldn’t care. She just wanted to go down on them, pin them and show them what she could do with this new body…

Not only that, but any actual evidence that she had been a kitten just moments prior were completely erased as a pair of antennae appeared atop of her head, completing her transformation into this other version of herself. And thus, the lights that had paralyzed her with heat and pure lust died down, letting the newly reborn girl stumbled her way out of the machine with a slick trail of juice running down her leg.

“Well, that seemed to work out great.” Akashi purred as she licked a kitty-shaped ice soda pop, her ears twitching in a dull manner after being faced with this display. “How do you feel? Ready to go sweep the Admiral off his fee-”

She didn’t get to finish that sentence, nor her pop, as it flew into the air from her body being rammed into. The next thing she saw was the girl’s bright green heart-filled eyes as she pinned her to the ground, her knee rubbing up against her crotch while an unnatural warmth radiated off her body…

The green-haired cat hadn’t expected this. Nor had she expected how her hair started to lose its natural color, her own body affected by the same heat that had transformed her friend. Maybe she shouldn’t have turned everything up to full… not that she could think about something so important for much longer, a trail of drool running down her cheek as her own transformation progressed.

Once Mutsu was done with her kitty friend and after she got to have a nice, mind-breakingly perfect orgasm, then she’d move on to try and find her dearest sister. And of course, since she was no doubt not really her sister, she’d just have to turn her into her sister. With a few kisses, a bunch of gropes and a bunch of rubbing so that warmth could really soak into her. Then she’d be her strong and loving Nagato, ready to give all of that and more back to her.

The thought of pleasing her Admiral and her distaste for huge tits faded into nothingness as Mutsu let herself be consumed by her lust, a bimbo barely resembling her former self. And the start of many more transformations, just like hers!

The Admiral had a tough job on his hands, turning all of his girls back to normal…
